       tinydns - a DNS server.


       tinydns  accepts  iterative DNS queries from hosts around the Internet,
       and responds with locally configured information.


       This  is  a  reference  page.   For  tutorial  information,   see   the
       instructions for
       running a DNS server (

       Normally tinydns is set up by the tinydns-conf(8) program.

       tinydns   runs  chrooted  in  the  directory  specified  by  the  $ROOT
       environment variable, under the uid and gid specified by the  $UID  and
       $GID environment variables.

       tinydns  listens  for incoming UDP packets addressed to port 53 of $IP.
       It does not listen for TCP queries.

       tinydns answers queries as specified by data.cdb, a binary file created
       by tinydns-data(8).

Further details

       tinydns  rejects zone-transfer requests, inverse queries, non-Internet-
       class queries, truncated packets, and  packets  that  contain  anything
       other than a single query.

       tinydns,  like  BIND, includes NS records with answers to most queries.
       This increases DNS packet sizes, but it draws queries away from  parent
       servers,  and  reduces  the  frequency  of  long  DNS delays.  With the
       default tinydns-data(8) cache times, a client that uses a normal record
       at  least  once every day will always have the corresponding NS records
       cached and will never have to talk to parent servers.
